SELF-TH READING LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 503,851, dated August22, 1893. Application filed October 29, 1892. Serial No. 450.408. (Nomodel.)

To all whom it may concern.-

Be it known that I, STEPHEN M. HAMBLIN, a citizen of the United States,residing in New Bedford, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Self-Threading Loom- Shuttles, of which the following is a full, clear,exact, and concise description, reference being had to the accompanyingdrawings, in which similar letters refer to similar parts throughout theseveral views.

This invention relates to an improvement in weavers shuttles, andconsists in the novel construction and arrangement of parts of such ashuttle, as will be hereinafter fully described in the specification,and more particularly pointed out in the claim.

In the accompanying drawings Figure 1 is an elevation of a side of ashuttle body showing a port, thread way and thread entry. Fig. 2, is anelevation partly in section showing theinternal construction of thoseportions embodying my invention.

At any convenient point in the side of the shuttle body A preferablynear its head and opposite the intended location of the delivery eye F Imake an opening or thread entry 0. extending through the shuttle bodysufficiently large to admit of the insertion of the eye F. and of thepassage of thread from one side of the shuttle out at the other. Themouth or entrance of such thread entry is cut away to form a funnelshape entrance for the reception of a loop, bight or loose mass ofthread. On the same side of the shuttle I make an opening or port D.completely through the wall of the shuttle body preferably at a rightangle to the point of the spindle sufficiently large to admit of pushingan end of the thread from the cop by the operatives finger from theinside of the wall to the outside. The thread-entry C and such port areconnected by means of a deep continuous slot, groove or threadway E.extending inwardly to the median line in the shuttle opposite to thepoint of the spindle so that a thread following such groove shall be conducted from its delivery at the point of the spindle into the transverseopening leading into the delivery eye F. The shuttle may be thread wayin one side,

provided with an ordinary delivery eye, but it will be noticed from theconstruction shown in Fig. 2 that I use preferably a metallic eye havingthe form of a hollow screw or cylinder provided with serrated sideswhich may be inserted through the thread entry 0. into its properposition and by internal distension with any suitable means be embeddedinto the shuttle body, and both the outer end m and the inner end aeyeleted out to prevent displacement. The extreme interior surfaces ofmy thread way when cut integral with the shuttle body serve as a conduitfor the thread when is use, but it is apparent that other 1nteriorthread-conductors may be affixed to any shuttle body having such port,entry and and an opposite delivery eye, with substantially a likeresult. My lateral threadway may be enlarged to any desirable extenteither for coarse yarns or to admit the insertion of the ordinaryfrictional tension devices upon its sides.

The operation of threading the shuttle 18 performed by passing the freeend of the thread by the tip of a finger from the inside of the shuttlebody outwardly through the port D. Such end is then caught with thefingers of the other hand and either inserted into the entry 0 until itprotrudes from the other side at the delivery eye F.; or a bight, orloop may be deposited in the entry 0. and thence led out at the eye F bythe hook in ordinary use; or a loose mass of the thread collected in theordinary manner used heretofore for threading by inhalation be insertedin; the entry 0 when itmay either be drawn through with slight effort bysuction applied to the eye F. or readily blown through by applying themouth to cover the entry 0. In either case the end protruding from theeye F. is drawn taut, which causes the thread to slide in the threadwayE. to the full extent into the conduit 0 in the center of the shuttle,when the shuttle is ready for use.

I do not desire to limit myself to the exact forms or relative positionsof the parts herein indicated, as it is obvious that they may bemodified in size shape and location with the same result.

What I claim as new, and desire to'secnre by Letters Patent, is-' v Ashuttle-body having a funnel-shaped thread entry or opening 0 madetransversely 5 through its head and terminating about midway of thetransverse diameter of the said body, an eye F communicating with thesaid opening and extending transversely through the body to the sideopposite that into which [O the said entry opens, a port D extendingthrough'the wall of the shuttle-bodmand a horizontal slot or'thre'adwayF- extending inward to a point in line with the end of the spindle andconnecting the entry 0 with the port D, substantially as described.

"ST HAMBLIN.
